A process for continuously preparing high density detergent composition is provided. The process comprises the steps of: (a) agglomerating a detergent surfactant paste and dry starting detergent material in a high speed mixer/densifier to obtain agglomerates having a Dispersion Index in a range of from about 1 to about 6, wherein Dispersion Index=A/B A is the surfactant level in the agglomerates having a particle size of at least 1100 microns, and B is the surfactant level in the agglomerates having a particle size less than about 150 microns; (b) mixing the agglomerates in a moderate speed mixer/densifier to further densify, build-up and agglomerate the agglomerates; and (c) conditioning the agglomerates such that the flow properties of the agglomerates are improved, thereby forming the high density detergent composition.

A process for preparing high density detergent composition comprising the steps of: (a) agglomerating a detergent surfactant paste and dry starting detergent material in a high speed mixer/densifier to obtain agglomerates, wherein said dry starting detergent material comprises a builder selected from the group consisting of aluminosilicates, crystalline layered silicates, sodium carbonate, Na2Ca(CO3)2, K2Ca(CO3)2, Na2Ca2(CO3)3, NaKCa(CO3)2, NaKCa2(CO3)3, K2Ca2(CO3)3, and mixtures thereof; (b) controlling the flow rate and temperature of said surfactant paste and said dry starting material and the residence time, speed, and mixing tool and shovel configuration of said high speed mixer/densifier such that said agglomerates have a Dispersion Index in a range of from about 1 to about 6, wherein Dispersion Index=A/P A is the surfactant level in said agglomerates having a particle size of at least 1100 microns, and B is the surfactant level in said agglomerates having a particle size less than about 150 microns; (c) mixing said agglomerates in a moderate speed mixer/densifier to further densify, build-up and agglomerate said agglomerates; and (d) conditioning said agglomerates such that the flow properties of said agglomerates are improved, thereby forming said high density detergent composition having a density of at least about 650 g/l.
